RADIATOR.

Specification of Letters Patent.

Patented Nov. 1, 1921.

Application filed June 7, 1916. Serial No. 102,254.

To all whom it may concern:

Be it known that I, OSCAR E. VVERNEKE, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Radiators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 7

This invention relates to improvcments in radiators and has for its primary object to provide an improved and. efficient radiator primarily designed for cooling the water of the cooling system of explosive engines in connection with motor vehicles.

With this and other objects in view, the invention consists in the novel construction, combination and arrangement of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawing, in which:

Figure 1, represents a front elevation of the improved radiator, partly in section,

Fig. 2 represents a transverse sectional View on the line 22 of Fig. l, and

Fig. 3 represents a fragmentary perspective view, partly in section, of. one of the units of the radiator removed.

Referring to the drawing in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 5 indicates generally the body of the radiator in which is arranged a plurality of pairs ofcorrugated vertically disposedplates 6. The front and rear edges of the plates 6 are brought together, as indicated at 7 and soldered or otherwise secured to presentza water-tight joint, and the medial portions of the plates of each pair are formed with opposed depressions 8 providing a vertical water channel 9. The. portions of the plates 6 intermediate the depressions 8 are formed with relatively shallow corrugations 10, for a purpose which will hereinafter apear. p Between each pair of plates 6, is arranged a pair of plates 11 of a second series, the plates 11 of each pair being oppositely disposed and formed with relatively deep bends or corrugations 12, which are engaged. in and supported by the corrugations 10 of the plates 6 to increase the strength and rigidity of the radiator. The plate 11 of each pair are spaced to present a vertical water passage 13 which communicates with the several lateral or horizontal passages 14 defined by the corrugations 12, and the front and rear edges of the plates 11 are brought together, as indicated at 15, and soldered or otherwise secured to present a watertight joint. As clearly shown in Fig. 1, the corrugations 12 of'the respective plates 11 of each pair are arranged in horizontal alinement and in vertically spaced relation, thereby forming a series of horizontal air passages 16, designed to effectively cool the several plates 11 and G and the wa-ter or other fluid circulating through the water passages 9, 13 and 14.

The webs, or vertically disposed portions, of each palr of plates 11, between the corrugations 12, are oppositely bulged, as indicated at 12, to increase the capacity of the ra diator and also to increase the radiating surface thereof.

What I claim is: p A radiator of the class specified comprising pairs of plates disposed to form water channels, the plates of each pair being similarly formed and comprising regularly spaced.

outwardly extending alined crimps, and having the portions intermediate the crimps ,out-

wardly bulged, the longitudinal edge portions of the plates of each pair being brought together and sealed and the ends'being open, and other pair of plates intermediate the first mentioned pairs of plates, and having
